svn commit: r212727 - head/usr.bin/kdump

Author: rpaulo

New Revision: 212727
URL: http://svn.freebsd.org/changeset/base/212727

Log:
  When generating functions to print the arguments of system calls with
  bitwise parameters (e.g. mmap), print the syscall parameter value first.
  The resulting output looks like the %b specifier of printf(9).
  
  Before:
  mmap(0,0x8000,PROT_READ|PROT_WRITE,...
  After:
  mmap(0,0x8000,0x3<PROT_READ|PROT_WRITE>,...
